content that is compressed is not filtered. A maximum of 10 rules can be defined.
This page includes the following settings:
Content String
The text or keywords that match web page content to block. (Do not use characters ` " & ' # \)
Enable Schedule Rule
The name of a scheduling rule to apply to the filter, as configured on the Tools > Scheduling
page.
SPI settings
Stateful Packet Inspection (SPI) is the intrusion detection feature of the router that limits access
for incoming traffic. This feature is called “stateful” because it examines the contents of packets
to determine the state of the communications; that is, it ensures that the stated destination
computer has previously requested the current communication. This is a way of ensuring that all
communications are initiated by the recipient computer and are taking place only with sources
that are known and trusted from previous interactions.
When an SPI violation occurs, the offending client is disconnected from the router for 30
minutes. When DoS attacks occur, the router’s Alert LED flashes until the attack ends.
